4 LIQUID-TREATING Application filed Jiine 27,

To all whom 'it may concern:

Be it known that 1 KENT W. Bau'rnn'rr. citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have ilifGlltOClJ. certain new and useful, Improvement in Liquid-Treating .-\pparatus, of which the following. is a full,

clear, concise, and exact description, retervertical sectional view on a larger scaleof a part of the mechanism shown in Fig. 1; and Fig. 3 1s a vertical sectional view on a nism shown in Fig. 1. A Like parts are indicated by similar'charactors of reference throughout theldiflerent aflhesettling tank a is .of anj well known or suitableconstruction. The water that is to'be treated flows from the spout 1) into the settli'ngtank, this spout communicating withjtheinterior of a water wheel casing 0 intowhich -water is'admitted from a pipe dciimmunicating with any suitable source of supply. An lovershot water wheel 0 is located within the casing so as to be im-- pinged upon by the'water just after it issues from: the pipe (i, this water wheel driving an agitator f in the settling tank vand agitators g in a chemical tank hi-na manner'whichis well known by those skilled in the art. The chemical is supplied to the settling tank through an admission pipe 2' that is in communication withj'an overflow opening ll: in the .chemical tank. this overflow opening determining the upper limit I ing level of the 5B "for operating the agitators f and' g,--th-is chemical in the chemical tank.

'The water flowing from the pipe of enters into'a'distributing box Z. A part of the -water flows from the distributing box through an adjustable orifice m that directs this part ofithc water onto the overshot water. wheel, whereby power is developed Specification of Letteis Patent.

water flowing through the 'spouth as has .been described. -Another portion of the water flows from the distributing hox through a pipe 12. which directs this swg-ond part of the water into a float tank 0. A. third part of the water flows through a valved opening. 72 into a dividing box 1, a baille wall 1" facing the pipe 8 that conveys the water from the opening 7) so a, to prevent the water from surging as it enters the dividing box. The only outlet. for the water to the'left of the ballle wall, as seen in Fig. 1, is over the batlie wall, the water describedby reterflowing over this baiile wall into the space to. the right thereof where it is comparatively free-of surging action. The portion of the bottom of the dividing box upon the right of the battle wall 1', as seen in Fig. 1 is provided with two apertures t and a (see Fig. 3) which overlie two chambers r and 'w. The chamber 10 is in communication with the chemical tank 12 by way of a pipe ,1 loading from the bottom of said. chamber. The chamber '0 is in coml'nunication with the .water wheel casing by means of a pipe 3 I the water flowing through said chamber 'c and pipe 3 finding access to the settling tank by way of the spout b. The elements y. r, t, u, v, w' and'y are supplied for engineering conveniences and are not absolutely indispensable; itbeing onl essential to provide a path for the water mm the valved opening p to'the chemical tank h. The amount of water that flows throngh the valved opening p is automatically regulated by a suitable regulating valve 1) that automatically varies the-carrying capacity of the orifice 7;. The valve p is regulated in its operation by a float that is connected with the valve 7/" b a valve cord or chain 2- passing over suitahle pulley mechanism. The orifice m and the admission orifice in the pipe n have certain predetermined fixed areas, while the orifice 72 is automatically regulable in six as has been set forth.

The water flows into the chemical tank by way of the pipe and occasions overflow of the fluid in the chemical tank into the settling tank through the chemical discharge orifice 70. pipe .1: is untreated water which obviously will weaken the chemical in the. chemical tank, and in order'to compensate for the re duction in the strength of the chemical in. the chemical tank, the supply of water flow The water flowing through the H tion in the strength vent-ion is the provision of a fixed flow ofin said float tank elevatin to the chemical'tank I: proper portion to'the Water flowing into the settling tank, this supply constant-1y increasing as the water is admitted to the settling tank. This result is accomplished by the portion of the water admitted through the pipe n into the'float tank 0,, the rising water the float z and correspondingly Withdrawing the'valve p from the opening p correspondingly toen large the opening y), the enlargement of said opening constantly progressing so constantly to increase the volume of water flowing through the pipe 01' andthereby constantly to incl-ease the volume of fluid'fio'wing through the discharge orifice is into the settling tank to compensate for the reducof the chemicalflowing from the chemical tank into t-he settling tank.

One important feature of my present inwater through the admission'device n so that the float e rises at a rate which is pro portional' to the water flowing-into the settling tank, whereby a constant factor is determined with which to calculate the-automatic adjustment of the valve 3). Another feature of li y invention resides in the tapered formation of the valve p, which tapered formation designedjso to vary the size of the opening as to fu'rnish'an increasing volume of water. through the pipe y-to compensate for the reduction in the strength of the chemical in the chemical tank h.

.I have shown a )ialvc structureo which maybe manually operated by a chain 0 in order to empty the water from the float tank into the settling tank when the water in said heattank has reached an upper limiting level, thereby to permit-the float mechanism to begin another cycleofadjusting opera.- tions.

In my application, Serial -No. 566,514, filed June 13, 1910, I have broadly claimed apparatus for accomplishing the results which are accomplishe by the apparatus of my present case, the present apparatus, in

an imits preferred embodiment, being my said provement upon theapparatus 0 co-pending application.

l-Vhile I have herein shown and'particularly described the preferred embodiment of my invention, I do not wish to be limited to the precise details of construction shown, as changesmay readily be made without departing from the spirit of'the inyention, but,

Having thusdescribed my f invent on, 1 claim as'new and desire to secure by letters, Patent the--foI1owing:-

the chemicaltank and cause the entmeans forv effecting 1. A liquid treating apparatus, including a settlin tank; a chemical tank; a float tank; in ependent means for conveying liquid to the chemical and float tanks; mochanism for e'fiecting increasing flow of liquid into .the chemical tank to displace liquid in flow thereof from the chemical tank to com pensate for the reduction of strength of the chemical in the chemical tank; and float mechanism in the fioat tank governingthe aforesaid mechanism.

2. A liquid treating apparatus, including a'settling tank; a chemical. tank; a regulating tank; independent means for conveying liquid to the chemical and. regulating tanks; mechanism for effecting increasing flow of liquid into the chemical tank to displace liquid-in the-chemical tank and cause the increased flow thereof from the chemical tank to compensate for the reduction of.

strength of the chemical inthe chemical tank; and regulating mechanism overned by the liquid in the regulating tan and in turn governing the operation of the aforesaid mechanism. '3. A liquid treatingapparatus, including a settling tank; a chemical tank; independpassage of two streams of liquid, one of which flows into the chemical tank; mechanism'for etl'ecting increasing flow of liquid into the chemical tank to displace liquid in the chemical tank and cause the increased flow thereof from the chemical tank to compensate for the re duction'of strength of thechemical in the chemical tankfand mechanism governed by the stream of liquid. companion to that increased which flows into the chemical tank and in turn governing the aforesaid mechanism.

4. A liquid treating apparatus, including a settling tank; a chemical tank; means for conveying liquid Ito the chemical tank; a

tapered plug valve for governing the volume of l uid flowing to the chemical tank; and liquidoperated mechanism operating the tapered plug valve to cause said valve to admit an increasing volume of liquid into the chemical tank to displace liquid in the chemical tank and cause the increased flow thereof from the chemical tank to compensate for the reduction of strength of the chemical in the chemical tank.
